Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1225-5GE42-0AA0
The Siemens 3VA1225-5GE42-0AA0 is a SENTRON 3VA1
series molded case circuit breaker (MCCB) engineered for dependable
protection of low-voltage electrical distribution systems against
overload and short-circuit faults. It is widely used in industrial
switchboards, PCC/MCC panels, commercial buildings, infrastructure projects,
and OEM power distribution systems where high fault interruption capability
and reliable operation are essential.
This MCCB is equipped with a thermal magnetic trip unit
(TM240 / ATFM – Adjustable Thermal Fixed Magnetic) that provides adjustable
overload protection and fixed magnetic short-circuit protection for enhanced
coordination and reliable fault clearing. The breaker belongs to the 3VA12
frame series and features a 4-pole configuration, making it suitable
for applications requiring phase and neutral protection.
With a rated current of 250A and a high breaking
capacity of 70kA at 415V AC, this MCCB is ideal for demanding industrial
and commercial electrical distribution systems with elevated fault-level
requirements.
